Los Angeles, Calif., a corporation of Nevada Application June 15, 1932,Serial No. 617,356 4 Claims. (Cl. 194-99) This invention relates toimprovements in multiple coin separator devices for use in combinationwith coin actuated mechanisms of various 1 types.

The general object of the invention is to provide an improved multiplecoin separator device which will separate spurious coins, slugs or otherobjects from good coins of the denomination intended to actuate themachine with which it is associated.

Another object of the invention is to provide a coin selecting deviceincluding a scavenger unit which separates objects of a shape differentfrom the shape of the coins intended to actuate the machine from objectsof the same shape as the good coins.

Other objects and the advantages of this invention will be apparent fromthe following description taken in connection with the accompanyingdrawings wherein:

and

Fig. 10 is a section taken on line 10-10 of Fig. 8.

Referring to the drawings by reference characters we have indicated ourimproved coin selecting device generally at 10. The device 10 isespecially adapted for use in combination with a coin actuatedmechanism, wherein two coins of different denominations are required toactuate the mechanism which in this instance are a dime and a'nickel.

As shown the device 10 comprises a scavenger unit 12, a dime coinselecting unit 14 and a nickel coin selecting unit 15. The scavengerunit 12 includes a center member 16 having cover plates 17 and 18secured thereto by screws 19. The center member 16 and the cover plates17 and 18 are made of a non-ferrous metal which is preferably die cast.On each face of the center member 16, we provide a pair of verticallyspaced downwardly inclined guide members 20 and 21 which form anentrance raceway 22 which directs objects placed therein rearwardlytowards an abutment member 23. 80

Below the abutment 23, we provide a selector member 24 which ispreferably made of steel and is shown as mounted on studs 25 integralwith the center member 16. Spaced forwardly of the selector 24, weprovide a vertical raceway 26 which is formed by guide members 27 and 28and which communicates with a rearwardly and downwardly inclined exitraceway 29 formed by guide members 30 and 31. Extending rearwardly andupwardly at an angle from the guide member 28, we provide a short guidemember 32. The space between the selector 24 and the guide member 32 isleft open to form a large scavenger exit indicated at 33.

The selector 24 is located and set at the correct angle so that coins ordisk shaped metal slugs upon leaving the point 34 of the guide member 20will strike the working face 35 of the selector and are directed acrossthe scavenger exit 33 into the vertical raceway 26 which will directthem into the exit raceway 29. Pieces of paper, cardboard, strips ofmetal, toothpicks, hair pins and other odd objects which might beinserted into the entrance raceway 22 upon leavingthe point 34 will falldownwardly and pass 35 out of the device 12 through the scavenger exit33.

The dime coin selecting unit 14 includes a back member 40 having a coverplate 41 secured thereto by screws 42 and which is retained in spacedrelation from the back member by raised portions on the back member suchas indicated at 43 to form a chamber 44. The back mem-- ber 40 and thecover plate 41 are made of a nonferrous metal which is preferably diecast. Adjacent the top of the device 14, we provide an entrance raceway45 which is formed by a pair of spaced rearwardly and downwardlyinclined guide portions 46 and 4'7.

The raceway 45 is adapted to direct undersized coins towards a verticalpassageway 48, the rear of which is formed by a guideportion 49. Theentrance to the vertical passageway 48 ,is formed by a selector 50 and aselector 51 both of which are made of steel and are mounted on studs 52integral with the back member 40. The selector 50 includes a deflectingpoint 53 and the selector 51 includes a similar point 54. Coins or metaldisks of the correct size on striking the selector points 53 and 54 inthe proper manner will be directed into a forwardly and downwardlyextending raceway 55, the top of which is formed by a guide portion 56and the bottom by a guide portion 5'7. The raceway 55 curves downwardlyas at 58 and communicates with rearwardly inclined raceway 59 the top ofwhich is formed by a guide portion 60 and the bottom by a guide portion61.

At the juncture of communication with the raceway 59 the raceway 55 alsocommunicates with a forwardly inclined raceway 62 the bottom of which isformed by a guide portion 63 and the top by a guide portion 64. At thejuncture of the raceways 55, 59 and 62 we provide a magnet or magnetizediron block 65 which includes a rounded end portion 66 which'forms asmall portion of the bottom of the raceway 55 and a small portion of thetop of the raceway 59.

The vertical passageway 48 communicates with a forwardly inclinedraceway 67 and the raceway 59 also communicates with the raceway 67,opening thereinto at the forward side. The rear of the receway 67 isformed by a guide portion 68 and the front is formed by a guide portion69.

The raceway 62 communicates with a downwardly and slightly rearwardlyinclined raceway 70 the rear of which is formed by a guide point 71 andthe front by a guide portion 72. The raceway 70 communicates with araceway 73 which includes a rearwardly curved section 74 and a straightrearwardly and downwardly inclined section 75. One side of the curvedsection 74 of the raceway '73 is formed by a guide portion 76 and theother side by a guide portion 77 and the top of the straight section isformed by a guide portion 78 and the bottom by a guide portion '79. Theupper end of the curved section 74 of the raceway '75 is offset from theraceway '70 to the rear thereof thus forming a shoulder 80 at thejuncture of the raceways 70 and '73.

Good dimes upon leaving the raceway 73 fall downwardly and are guided bya selector 81 into a rearwardly and downwardly inclined raceway 83 whichcommunicates with a vertical exit raceway 84. The top of the raceway 83is formed by a surface 85 of a selector 86 and the bottom by a guideportion 87. The rear of the exit raceway 84 is formed by a guide portion88 and the front is formed by a guide portion 89.

Some spurious coins upon leaving the raceway 73 strike either thesurface 90 or the point 91 of the selector 86 and are directed into aforwardly and downwardly inclined raceway 92 which directs them into areject raceway 93. The bottom "'of the raceway 92 is formed by a guideportion 94, and .the front of the reject raceway 93 is formed by a guideportion 95. Other spurious coins upon leaving the raceway 73 strike anabutment portion 96 and the face 90 of the selector 85 and are directedinto the raceway 92.

The selectors 81 and 85 like the selectors 50 and 51 are mounted onstuds 52 which are integral with the back member 40. Adjacent thestraight section 79 of the raceway 73, we provide a horse shoe magnet97, the poles 98 and 99 of which are positioned across the raceway '73at approximately right angles thereto with the faces of the poles flushwith the inner face of the cover plate 41. Opposite the magnet 97 weprovide an armature plate 100, the inner face of which is flush with theface of the raceway formedby the back 40. The magnet 97 is shown asmounted in a bracket 101 which is secured in position by screws 102which engage the armature plate 100. The bracket 101 like the back 40and the cover 41 is made of nonferrous metal and is preferably die cast.

The armature plate 100 causes the magnetic field to travel from one ofthe magnet poles straight across the raceway 73 into the armature plateand thence from the armature plate straight across the raceway 73 to theother pole of the magnet.

Good dimes entering the entrance raceway 45 of the device 14 from theexit raceway 29 of the scavenger device 12 pass downwardly through theraceway 45 and strike the working point 53 of the selector 50 fromwhence they are directed into the raceway 55. As they leave the raceway55 they strike the guide portion 63 and pass through the raceway 62 intothe raceway 70 wherein they strike the shoulder 80 which momentarilystops them causing them to joggle so that each coin enters the curvedsection 74 of the raceway 73 at approximately the same speed. As a dimepasses between the poles of the magnet 97 and the armature plate 100 thecurrent produced in the dime by the dime passing through the magneticfield between the magnet poles 98 and 99 and the armature plate 100retards the dime sufliciently so that it does not strike the selector 85but strikes the face of the selector 81 which directs it into theraceway 83 from which it passes into the exit raceway 84.

Iron and steel disks entering the enrtance raceway 45 pass downwardlytherein and strike the point 53 of the selector 50 and are directed intothe raceway 55. As these ferrous disks are directed downwardly towardthe raceways 59 and 62 they are attracted to the magnetic bar 65 andengage the rounded end 66 thereof which directs them into the raceway 59as the momentum and weight of the disks disengage them from the magneticbar 65. These ferrous disks then pass through the raceway 59 and enterthe raceway 67 and are directed downwardly thereby towards the raceway92.

Some other non-ferrous spurious disks after passing through the entranceraceway 45 strike the selector 51 to the rear of the point 54 and aredirected into the passageway 48 and thence into the raceway 67.

Other non-ferrous spurious disks which may have the same resilience as adime strike the point 53 of the selector 50 and are directed into theraceway 55 and thence are directed through the raceways 62 and 70 intothe raceway 73. As these spurious disks pass through the magnetic fieldbetween the poles of the magnet 97 and the armature plate 100 theirmomentum is either increased whereupon they strike the abutment 96 andare thereafter directed into the raceway 92 or they are retardedsufliciently to cause them to fall straight downwardly onto the guideportion 94 whereupon they enter the raceway 92.

All spurious disks upon leaving the raceway 67 either strike theselector 86 and are directed into the raceway 92 or strike forwardly ofthe upper point of the selector 81 and are directed into the raceway 92.

The raceway 84 into which good dimes are directed may communicate with acoin chute 104 which directs the coins to the coin actuated mechanism ofthe machine with which the device is associated and the raceway 93 intowhich spurious disks are directed may communicate with a chute 105 whichmay either direct the spurious disks out of the machine or into asuitable receiver. (See Fig. 1.)

The nickel coin selecting unit 15 includes a back member 110 having acover plate 112 secured thereto by screws 113 and which is retained inspaced relation from the back member by raised portions on the backmember such as indicated at 114 to form a chamber 115 between the backand the cover. The back member 110 and the cover plate 112 are made of anonferrous metal which is preferably die cast.

Adjacent the top of the device 15, we provide an entrance raceway 116which is formed by a pair of spaced rearwardly and downwardly inclinedguide portions 117 and 118. The entrance raceway 116 directs coins andspurious disks towards a passageway 117' the entrance of which is formedby a point 118 of a selector 119 and a point 120 of a selector 121. Theselectors 119 and 121 are shown as mounted on studs 122 which areintegral with the back member 110. The entrance raceway communicateswith a forwardly and downwardly inclined raceway 123 which curves into avertical raceway 124. The bottom of the raceway 123 is formed by amagnetic bar 125, the end of which adjacent the raceway 124 is roundedas at 126. The top of the raceway 123 is formed by a guide portion 127and the front of the raceway 124 is formed by a guide portion 128.

Communicating with the raceway 124 and inclined forwardly and downwardlyfrom the rounded end 126 of a magnetic bar 125, we provide a raceway129. The top of the raceway 129 is formed by a guide portion 130 and thebottom by a guide portion 131. Both the passageway 117' and the raceway129 direct articles into a forwardly and downwardly reject raceway 132,the rear of which is formed by a guide portion 133 and the front by aguide portion 134,

The raceway 124 communicates with a raceway 135 which includes a curvedsection 136 and a straight rearwardly and downwardly inclined section137. At the juncture of the raceway 135 and the raceway 124 the raceway135 is ofiset to the front as indicated at 138. At the juncture of theraceway 135 and the raceway 129 we provide a shoulder 139, the forwardpoint of which extends forwardly of the rounded end 126 of the magneticbar 125.

The raceway 132 directs articles passing therethrough across the path ofthe raceway 135 into a forwardly and downwardly inclined raceway 140which communicates with a vertical exit raceway 141. The bottom of theraceway 140 is formed by a guide portion 142 and the front of thevertical raceway 141 is formed by a guide portion 143.

The raceway 135 directs articles across the path of the raceway 132towards a vertical raceway 145, the front of which is formed by aselector 146 which is mounted on studs 147 integral with back 110. Theselector 146 includes an upper point 148 and a face 149 inclineddownwardly and rearwardly therefrom and an approximately verticallyextending race 150 which forms the front guide portion of the raceway145. The rear of the raceway 145 is formed by a guide portion 151 whichis integral with the cover plate 112.

Adjacent the straight section 137 of the raceway 135, we provide a horseshoe magnet 153, the poles 154 and 155 of which are positioned acrossthe raceway 135 at approximately right angles thereto with faces of thepoles flush with theinner face of the cover plate 112. Opposite themagnet 153, we provide an armature plate 156, the inner face of which isflush with the side of the raceway 135. The magnet 153 is shownasmounted in a bracket 15'] which is secured in position by screws 158which engage the armature plate 156. The bracket 157 like the back 110and the cover 112 is made of nonferrous metal and is preferably diecast.

Good nickels entering the coin selecting unit 15 from the scavenger unit12 enter the raceway 116 and pass therethrough. As a good nickel emergesfrom the raceway 116 it strikes the point 118 and is directed throughthe passageway 117 into the raceway 123 which directs it into thevertical raceway 124. As it reaches the juncture of the raceway 124 andthe raceway 135 it strikes the shoulder 139 thereby momentarily stoppingthe coin as it joggles before entering the raceway 135. Thus each coinentering the raceway 135 does so at approximately the same speed. As thenickel passes between the poles of the magnet 153 and the armature plate156 the current produced in the nickel by the nickel passing through themagnetic field between the magnet poles 154 and 155 and the armatureplate 156 acts on the nickel to decrease its momentum just sufiicientlyto carry it over the point 148 of the selector 146 and into the exitraceway 145.

Iron and steel disks entering the raceway 116 pass downwardly thereinand strike the point 118' of the selector 119 and are directed acrossthe passageway 117' into the raceway 123. As these ferrous disks passfrom the raceway 123 into the vertical raceway 124 the attraction of themagnetic bar 125 causes the momentum of the disks to swing them into therearwardly inclined raceway 129. After passing through the raceway 129they enter the raceway 132 which directs them downwardly into theraceway 140 from whence they enter the vertical reject raceway 141.

Other non-ferrous spuriousdisks which may have the same resilience as anickel strike the point 118' of the selector 119 and are directedthrough the raceways 123 and 124 into the raceway 135 in the same manneras a good nickel. As these spurious disks pass through the magneticfield between the poles of the magnet 153 and the armature plate 156their momentum is retarded more than a nickel coin whereupon as theyleave the raceway 135 they fall downward into the raceway 140 whichdirects them into the reject raceway 141.

1 The raceway 145 into which good nickels are directed may communicatewith a coin chute 160 which directs the coins to the coin actuatedmechanism of the machine with which the device is associated and theraceway 141 into which spurious disks are directed may communicate witha chute 161 which may either direct the disks out of the machine or intoa suitable receiver.

Undersized nickels pass the points 118 and 120 and go to the raceway 132whence they pass to the raceway 140 to the reject raceway 141.

When assembling the units 12. 14 and 15 to make the complete coinselector 10. the units 14 and 15 are secured together by bolts and nut163 (see Fig. 1) at the points indicated at 164 in Figs. 5 and 8. Afterthe units 14 and 15 have been secured together the cover plate 17 of thescavenger 12 is secured by bolts 165 to the back member 40 of the unit14 at the points indicated at 166 in Figs. 3 and 5 and the cover plate18 of the scavenger unit is secured to the back member 110 of the unit15 by bolts similar to the bolts 165 at the points indicated at 167 inFig. 8.
